I agree, but B2 was not defending A1.

4-24-4a says

ART. 4 . . . Guarding an opponent with the ball or a stationary opponent without
the ball:
a. No time or distance is required to obtain an initial legal position.

This does not necessarily apply when B2 is not defending A1. Is there another rule that applies to an inadverdent collision, or a collision caused by the ball carrier?
